MAX3514 Overview
Description
The MAX3514/MAX3516/MAX3517 programmable-gain amplifiers are designed for use in CATV upstream applications. The MAX3514/MAX3517 drive up to +61dBmV (QPSK) into a 75Ω load when driven with a +34dBmV nominal input signal.
Key Features
- provides greater than 56dB of dynamic range, which is controlled by an SPI™ 3-wire interface
- Gain control is available in 0.5dB steps
- The devices operate over a frequency range of 5MHz to 65MHz
- The MAX3514 is a pin-for-pin compatible upgrade for the MAX3510
- Like the MAX3510, the MAX3514 is internally matched for use with a 2:1 (voltage ratio) balun
- The MAX3517 utilizes an external output resistor for greater load-matching flexibility, and offers the same performance as the MAX
